1Value Line and LicensingThe SilkWorm 3250/3850 Hardware Reference Manual is valid for all versions of the switch: SilkWorm 3250 VL2, 3850 VL2, 3850 VL4, and Full Fabric licensing. The license is preloaded according to the switch you ordered. The Value Line option is a set of switches based on existing Brocade product lines but with limits placed on the number of domains that can be used.

For the SilkWorm 3850 you can purchase a 2-domain limit or a 4-domain limit. The SilkWorm 3250 offers a 2-domain limit option.

Value Line switches provide the same Brocade quality within a limited-domain fabric. Value Line products can be upgraded by license; refer to the Fabric OS Procedures Guide to learn how to upgrade a license. To see the type of licensing your SilkWorm 3250/3850 runs, use the licenseshow command.Exampleswitch:root> licenseshow XXXnnXXnXnnXXX: Fabric Watch license Release v4.2 license XXXnnXXnXnnXXX: Zoning license XXXnnXXnXnnXXX: Web license XXXnnXXnXnnXXX: 2 Domain Fabric license

3250/3850 Switch ComparisonThe basic difference between the SilkWorm 3250 and the SilkWorm 3850 is the number of ports: the SilkWorm 3250 contains 8 ports, while the SilkWorm 3850 contains 16. The SilkWorm 3250 contains only 1 power supply while the SilkWorm 3850 has built-in redundancy and contains 2 power supplies; thus, the SilkWorm 3850 also weighs more. The Silkworm 3850 can operate indefinitely on either one of its redundant power supplies.

Switch CharacteristicsThe next few sections describe the physical characteristics of the SilkWorm 3250/3850 and some important requirements for proper operation.

Port Side of the SilkWorm 3250/3850You can see the physical differences between the Silkworm 3250 and the SilkWorm 3850 switches in the following figures. The most noticeable difference is the number of ports. Figure 1-1 shows the port side of the SilkWorm 3250, and Figure 1-2 shows the port side of the SilkWorm 3850. All LEDs are on the port side of the switch: the nonport side is used for serial number labeling and to allow the free flow of air. The Silkworm 3850 enclosure has forced-air cooling, with the fans pushing the air from the nonport side of the chassis through the enclosure, and exhausting to the port side. A complete description of the locations and interpretations of these LEDs can be found at Interpreting LED Activity on page 3-1. Figure 1-1AC Power Receptacle

Installation and Safety ConsiderationsYou can install the SilkWorm 3250/3850 in three ways: 1. 2. 3. As a stand-alone unit on a flat surface. In an Electronic Industries Association (EIA) cabinet using a fixed-rail rack mount kit, which is provided with the switch. In an EIA cabinet using an optional slide-rail rack mount kit. The optional slide-rail rack mount kit can be ordered from your switch retailer. When mounting into a slide-rail rack, you can mount the chassis to slide from either the port side or the nonport side.

SilkWorm 3250/3850 Hardware Reference Manual Publication Number 53-0000623-01

2-3

2Electrical ConsiderationsFor successful installation and operation of the switch, ensure that the following electrical requirements are met. For power supply information, refer to System Specifications on page A-3.

Primary AC input 100-240 VAC (switch auto-senses input voltage), 47-63 Hz. Correctly wired primary outlet, with circuit protected by a circuit breaker and grounded in accordance with local electrical codes. Adequate supply circuit, line fusing, and wire size, as specified by the electrical rating on the switch nameplate.

Environmental Considerations At a minimum, adequate cooling requires that you install the switch with the non-port side, which contains the air intake vents, facing the cool-air aisle. Verify that a minimum of 24 cubic ft/minute of air flow is available to the air intake vents on the nonport side of the switch. Verify that the ambient air temperature does not exceed 40 C (104 F) while the switch is operating. If installing the switch in a cabinet: - The cabinet must be a standard EIA cabinet. - Plan a cabinet space that is 1 rack unit (1.75 inches; 4.45 cm) high, 19 inches (48.3 cm) wide, and at least 30 inches (76.2 cm) deep. - Ground all equipment in cabinet through a reliable branch circuit connection and maintain ground at all times. Do not rely on a secondary connection to a branch circuit, such as a power strip. - Ensure that airflow and temperature requirements are met on an ongoing basis, particularly if the switch is installed in a closed or multicabinet assembly. - Verify that the additional weight of the switch does not exceed the cabinets weight limits or unbalance the cabinet in any way. - Secure the cabinet to ensure stability in case of unexpected movement, such as an earthquake.

Installing a Stand-Alone SilkWorm 3250/3850To install the SilkWorm 3250/3850 as a stand-alone unit, follow the procedure described here: 1. 2. Unpack the SilkWorm 3250/3850 and verify that all items listed on page 2-4 are present and undamaged. Apply the adhesive rubber feet. Applying the rubber feet onto the switch helps prevent the switch from sliding off the supporting surface. a. b. Clean the indentations at each corner of the bottom of the switch to ensure that they are free of dust or other debris that might lessen the adhesion of the feet. With the adhesive side against the chassis, place one rubber foot in each indentation and press into place.

2-4

SilkWorm 3250/3850 Hardware Reference Manual Publication Number 53-0000623-01

23. 4. Place the switch on a flat, sturdy surface. Provide power to the switch as described in Powering the SilkWorm 3250/3850 On and Off on page 3-1.

Caution Do not connect the switch to the network until the IP address is correctly set. For instructions on how to set the IP address, see Cabling and Configuring the SilkWorm 3250/3850.

Installing a SilkWorm 3250/3850 Into an EIA CabinetThe rack mount kit can be installed in two ways:

To allow the port side of the switch to slide out of the exhaust-air side of the cabinet. In this installation, the port side of the switch is flush with the edge of the cabinet. To allow the nonport side of the switch to slide out the cool-air side of the cabinet. In this installation, the port side of the switch is set 3 in. (7.62 cm.) back from the edge of the cabinet, allowing a more gradual bend in the fiber optic cables.

Whichever mounting method you choose, follow the installation instructions shipped with the appropriate rack mount kit:

To install the switch into a fixed-rail rack (default with the SilkWorm 3250/3850), refer to the Fixed Rack Mount Kit Installation Procedure (53-0000244-03). To install the switch into a slide-rail rack, refer to the Slide Rack Mount Kit Installation Procedure (53-0001625-06).

Cabling and Configuring the SilkWorm 3250/3850The SilkWorm 3250/3850 must be configured to ensure correct operation within a network and fabric. For instructions about configuring the switch to operate in a fabric containing switches from other vendors, refer to the Brocade Fabric OS Procedures Guide. For more information about the commands used in this procedure, refer to the Brocade Fabric OS Reference Manual.

Recommendations for Cable ManagementThe minimum bend radius for a 50 micron cable is 2 inches under full tensile load and 1.2 inches with no tensile load. Cables can be organized and managed in a variety of ways: for example, using cable channels on the sides of the cabinet or patch panels to minimize cable management. Following is a list of recommendations:

Plan for rack space required for cable management before installing the switch. Leave at least 3.28 ft. (1 m.) of slack for each port cable. This provides room to remove and replace the switch, allows for inadvertent movement of the rack, and helps prevent the cables from being bent to less than the minimum bend radius.

SilkWorm 3250/3850 Hardware Reference Manual Publication Number 53-0000623-01

2-5

2 If you are using Brocade ISL Trunking, consider grouping cables by trunking groups. The cables used in trunking groups must meet specific requirements, as described in the Brocade Fabric OS Features Guide. For easier maintenance, label the fiber optic cables and record the devices to which they are connected. Keep LEDs visible by routing port cables and other cables away from the LEDs. Do not use tie wraps on fiber optic cables, because wraps are easily overtightened and can damage the optic fibers.

Power Supply SpecificationsThe power supplies are universal and capable of functioning worldwide without using voltage jumpers or switches. They meet IEC 61000-4-5 surge voltage requirements and are autoranging in terms of accommodating input voltages and line frequencies. Each power supply has its own built-in fan for cooling, pushing the air toward the port side of the switch. Power supplies are not removable. Table 2-3 lists the power supply specifications of the SilkWorm 3250/3850. Table 2-3 SilkWorm 3250/3850 Power Supply Specifications Value Correctly wired and earth-grounded Specification Outlet

In a UNIX environment, type the following string at the prompt: tip /dev/ttyb -9600

Power Up the Switch and Log InOnce a serial connection is established, provide power to the switch; power is supplied to the switch as soon as the first power supply is connected and powered on: 1. Connect the power cords to both power supplies and power sources. To protect against AC failure, connect the power cords to outlets on separate circuits. Ensure that the cords have a minimum service loop of six inches available at the connection to the switch and are routed to avoid stress. The power supply LED lights up green, and the switch begins running POST. POST should complete and the switch will complete the boot process in about three minutes. 2. 3. 4. After POST is complete, verify that the System Status and Power Status LEDs are green. Using a serial connection, when the terminal emulator application stops reporting information, press Enter to display the login prompt. Log in using the administrative account; the logon is admin and the default password is password. Up to two simultaneous admin sessions and four user sessions can be created.

2Step 2 - Set the IP AddressReplace the default IP address and related information with the information provided by your network administrator:. By default, the IP address is set to 10.77.77.77. 1. 2. Type ipaddrset at the terminal emulator application prompt. Type the requested information as prompted.Exampleswitch:admin> ipaddrset Ethernet IP Address [192.168.1.1]:10.32.53.47 Ethernet Subnetmask [255.255.255.0]:255.255.240.0 Fibre Channel IP Address [0.0.0.0]: Fibre Channel Subnetmask [0.0.0.0]: Gateway IP Address [0.0.0.0]:10.32.48.1 Set IP address now? [y = set now, n = next reboot]:y IP address being changed... Committing configuration...Done. switch:admin>

3. 4. 5.

Optionally, verify that the address was correctly set by entering the ipaddrshow command at the prompt. Record the IP address on the label clearly displayed on the port side of the chassis. If the serial port is no longer required, log out of the serial console, remove the serial cable, and replace the safety plug in the serial port.

Note Any time the port is not in use, the safety plug should be installed to protect it from foreign material.

Step 3 - Create an Ethernet Connection and Log InCreate an Ethernet connection to the SilkWorm 3250/3850: 1. Connect an Ethernet cable to the Ethernet port and to the workstation or to an Ethernet network containing the workstation. After this connection is made, the switch can be accessed remotely, by command line or by Brocade Advanced Web Tools. Ensure that the switch is not being modified from any other connections during the remaining steps. Log in to the switch by telnet, using the admin account.

2.

Step 4 - Modify the Domain ID (Optional)If desired, you can modify the domain ID. The default domain ID is domain 1. If the switch is not powered on until after it is connected to the fabric and the default domain ID is already in use, the domain ID for the new switch is automatically reset to a unique value. If the switch is connected to the fabric after is has been powered on and the default domain ID is already in use, the fabric segments. The domain IDs that are currently in use can be determined using the fabricshow command. The number of domains is determined by your domain fabric licensing.

SilkWorm 3250/3850 Hardware Reference Manual Publication Number 53-0000623-01

2-9

2To modify the domain ID: 1. 2. 3. Disable the switch by typing switchdisable. Type configure. This prompts display sequentially; type a new value or press Enter to accept each default value. At the Fabric Parameters prompt, type Y and press Enter:Fabric parameters (yes, y, no, n): [no] y

4.

Enter a unique domain ID, such as the domain ID used by the previous switch, if still available:Domain: (1..239) [1] 3

5. 6. 7.

Complete the remaining prompts or press Ctrl+D to accept the remaining default settings. Re-enable the switch by entering the switchenable command. Optionally, specify any custom status policies: a. b. Enter the switchstatuspolicyset command at the prompt. This command sets the policy parameters that determine the overall switch status. Customize the status policies as desired.

To deactivate the alarm for a particular condition, enter 0 at the prompt for that condition.

Step 5 - Install the SFP TransceiversIf your SilkWorm 3250/3850 came with uninstalled SFP transceivers, or if those transceivers have been removed, use the following procedure to install them into the Fibre Channel ports. A list of supported SFPs can be found in Table A-2 on page A-2. The ports selected for use in trunking groups must meet specific requirements. For a list of these requirements, refer to the Brocade Fabric OS Features Guide. To install SFP transceivers: 1. Position a transceiver so that it is oriented correctly and insert it into a port until the latching mechanism clicks. The transceivers are keyed to ensure correct orientation. If a transceiver does not install easily, ensure that it is correctly oriented. For instructions specific to the type of transceiver, refer to the transceiver manufacturers documentation. 2. Repeat for the remaining ports, as required.

2-10

SilkWorm 3250/3850 Hardware Reference Manual Publication Number 53-0000623-01

2Step 6 - Connect the CablesCaution The minimum bend radius for a 50-micron cable is 2 inches under full tensile load, and 1.2 inches with no tensile load. Because they are easily overtightened, tie wraps are not recommended for optical cables. Connect the cables to the transceivers: 1. The cable connectors are keyed to ensure correct orientation. Orient a cable connector so that the key (ridge on one side of connector) aligns with the slot in the transceiver and insert cable into transceiver until latching mechanism clicks. If a cable does not install easily, ensure it is correctly oriented. For instructions specific to cable type, refer to the cable manufacturers documentation. Repeat for the remaining transceivers, as required.

2.

The cables used in trunking groups must meet specific requirements. For a list of these requirements, refer to the Brocade Fabric OS Features Guide..

Verifying ConfigurationAfter completing the configuration, use the LEDs and commands to verify that the configuration has been accepted: 1. 2. 3. Check the LEDs to verify that all components are functional. For information about LED patterns, refer to Interpreting LED Activity on page 3-1. Verify the correct operation of the SilkWorm 3250/3850 by entering the switchshow command from the workstation. This command provides information about the switch and port status.

This chapter provides the following information:

Powering the SilkWorm 3250/3850 On and Off on page 3-1 Interpreting LED Activity on page 3-1 POST and Boot Specifications on page 3-7 Interpreting POST Results on page 3-8

Powering the SilkWorm 3250/3850 On and OffTo apply power to the SilkWorm 3250/3850, connect at least one power cable to an AC receptacle on the switch and to a power source. The switch runs POST (power-on self-test) by default each time it is powered on, reset, or rebooted, and requires as long as 3 minutes. To end the flow of power to the SilkWorm 3250/3850, remove the power cord from the power source. Note Removing all power from the switch triggers a system reset. All devices are returned to their initial state the next time the switch is powered on.

Interpreting LED ActivitySystem activity and status can be determined through the activity of the LEDs on the switch. There are three possible LED states: no light, a steady light, and a flashing light. The steady lights and flashing lights can be green or amber. The LEDs flash any of these colors during boot, POST, or other diagnostic tests. This is normal and does not indicate a problem unless the LEDs do not indicate a healthy state after all boot processes and diagnostic tests are complete.

POST and Boot SpecificationsWhen the switch is turned on or rebooted, the switch performs POST. Total boot time with POST is a minimum of 3 minutes. POST can be omitted after subsequent reboots by using fastboot. For more information about this command, refer to the Brocade Fabric OS Reference.

POSTThe success/failure results of the diagnostic tests that run during POST can be monitored through the error log or the command line interface. POST includes the following steps: 1. 2. 3. 4. Preliminary POST diagnostics are run. Operating system is initialized. Hardware is initialized. Diagnostic tests are run on several functions, including circuitry, port functionality, memory, statistics counters, and serialization.

BootBoot completes in approximately 3 minutes if POST is run. In addition to POST, boot includes the following steps after POST is complete: 1. 2. 3. 4. 5. 6. Universal port configuration is performed. Links are initialized. Fabric is analyzed, and if any ports are connected to other switches, the switch participates in a fabric configuration. Switch obtains a domain ID and assigns port addresses. Unicast routing tables are constructed. Normal port operation is enabled.

Interpreting POST ResultsPOST is a system check that is performed each time the switch is powered on, rebooted, or reset. During POST, the LEDs flash different colors. Any errors that occur during POST are listed in the error log. To determine that POST completed successfully and whether or not any errors were detected: 1. Verify that the switch LEDs indicate that all components are healthy. See Table 3-2 for description and interpretation of LED patterns. If one or more LEDs do not display a healthy state, verify that the LEDs on the switch are not set to beacon; use the switchshow command. Verify the switch prompt displays on the terminal of a computer workstation connected to the switch. If there is no switch prompt when POST completes, press Enter. If the switch prompt still does not display, try opening another telnet session or accessing through another management tool. If this is not successful, the switch did not successfully complete POST; contact your switch supplier for repair. Review the switch system log for errors. Any errors detected during POST are written to the system log, accessible through the errshow command.

Maintaining the SilkWorm 3250/3850The SilkWorm 3250/3850 does not require any regular physical maintenance; it was designed to minimize the chance of failure. Ensure that the environmental conditions, described in System Specifications on page A-3, are met. This helps prevent failure of the switch due to distress or abuse.

Installing an SFPIf your SilkWorm 3250/3850 did not come with installed SFPs, or you are replacing older ones, follow these instructions to install your SFP: 1. 2. Making sure that the bale (wire handle) is in the unlocked position, place the SFP in the correctly oriented position on the port, as shown in Figure 4-1. Slide the SFP into the port until you feel it click into place and close the bale.

4 Removing an SFPIn some cases you might need to remove an SFP transceiver, either because it is no longer needed or because you must replace it. To remove SFP transceivers: 1. 2. 3. 4. Press and hold the cable release, as shown in Figure 4-2. Remove the cable from the transceiver. Pull the bale (wire handle) to release the transceiver. Grasping it by the bale, gently but firmly pull the transceiver out of the port. Caution If the SFP you are removing does not have a bale, use a small implement such as a screwdriver to press the release trigger beneath the port. Non-baled SFPs can be damaged by the removal process and are not recommended. Refer to the Brocade Compatibility Matrix for a list of supported SFPs and devices. 5. Repeat this procedure for the remaining ports as required.

4 Diagnostic TestsIn addition to POST, Fabric OS includes diagnostic tests to help troubleshoot the hardware and the firmware. This includes tests of internal connections and circuitry, fixed media, and the transceivers and cables in use. The tests are implemented by command, either through a telnet session or through a terminal set up for a serial connection to the switch. Some tests require the ports to be connected by external cables, to allow diagnostics to verify the serializer/deserializer interface, transceiver, and cable. All diagnostic tests are run at link speeds of both 1 Gb/sec and 2 Gb/sec. Caution Diagnostic tests can temporarily lock the transmit and receive speed of the links during diagnostic testing. For information about specific diagnostic tests, refer to the Brocade Fabric OS Procedures Guide.

Fibre Channel Port SpecificationsThe Fibre Channel ports in the SilkWorm 3016 are compatible with SWL and LWL SFP transceivers. The strength of the signal is determined by the type of transceiver in use. The ports meet all required safety standards. For more information about these standards, see Regulatory Compliance on page A-5. The ports are capable of operating at 2.125 Gb/sec or 1.0625 Gb/sec, and are able to autosense the highest speed of which all attached devices are capable.

Serial Port SpecificationsThe serial port is located on the port side of the switch. It is a three-wire RS-232 port with a DB-9 male connector, designed to connect to a DTE port. Note To provide dust and ESD protection, keep the safety plug on the serial port whenever the port is not in use. The serial port can be used to connect to a computer workstation to configure the switch IP address without connecting to the fabric. The serial ports parameters are 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control. The port requires a straight (extension) serial cable with a female 9-pin subminiature-D connector. Only pins 2, 3, and 5 are supported.

Supported SFPsSFPs that have been tested and are known to work with the SilkWorm 3250/3850 are shown in Table A-2. Use only SFPs that are tested and supported. Do not use non-supported SFPs, as these can affect switch operability. They might not fit correctly and could void your warranty.
